Library Management System (LMS)

Library Management System (LMS) is a secure, modular web application built with Spring Boot and Spring Security, designed for library administrators to efficiently manage books, students, publications, and subscriptions. This project follows modern software engineering practices, including layered architecture, RESTful principles, and authentication best practices.

Project Overview

The LMS provides a centralized platform to perform administrative operations with security and auditability in mind. It facilitates:

• Book inventory and circulation management
• Student record tracking
• Vendor and publication management
• Subscription and reporting management
• Secure profile and credential management

The system is built to support single-user administrative workflows, with future extensibility for role-based access if required.

Key Features

• Authentication & Security

  • Secure login using Spring Security.
  • Session-less authentication context with UsernamePasswordAuthenticationToken.
  • Encrypted password storage with BCryptPasswordEncoder.
  • Built-in protection against unauthorized access.

• Administrative Dashboard

  • Real-time operational metrics for books, students, and vendors.
  • Summary analytics for issued, available, and overdue books.
  • Daily quotes and system notifications.

• Data Management

  • CRUD operations for books, students, vendors, and publications.
  • Password reset and profile update functionality.
  • Audit-ready record management for administrative operations.

• Web Interface

  • Frontend built with Thymeleaf for server-side rendering.
  • Responsive design compatible with modern devices.
  • Dynamic UI elements like password toggle, alerts, and form validation.

• Extensibility

  • Modular services for user management, reporting, and operational workflows.
  • Prepared for future multi-role access and REST API integration.

Architecture & Design

• Layered Architecture

  • Controller Layer – Handles HTTP requests and session management.
  • Service Layer – Encapsulates business logic for users, books, and reports.
  • Repository Layer – Data persistence using Spring Data JPA with MySQL.
  • Security Layer – Spring Security handles authentication and authorization.

• Security & Session Management

  • Authentication via UsernamePasswordAuthenticationToken.
  • Role-agnostic security (single-user administration).
  • Stateless session context maintained by Spring Security.

• Persistence

  • Relational database schema using MySQL.
  • Entities mapped with JPA/Hibernate annotations.
  • Repository pattern for clean and testable database access.
